What is FrankenPHP?
FrankenPHP is a modern PHP application server written in Go, designed to simplify PHP deployment and enhance performance. It embeds the official PHP executor within the state-of-the-art Caddy web server, providing native support for HTTP/1.1, HTTP/2, and HTTP/3 protocols. The tool automates HTTPS certificate generation and renewal through Let's Encrypt or ZeroSSL, requiring minimal configuration—users simply copy PHP files to the document root. It supports popular PHP extensions like OPcache and XDebug, and offers features such as worker mode, which keeps applications in memory for faster request handling, and early hints to improve website load times.
FrankenPHP enables building standalone, self-executable binaries for PHP web applications and command-line tools, eliminating dependencies. It includes built-in support for modern compression formats (Brotli, Zstandard, Gzip), structured logging, Prometheus metrics, tracing, and a Mercure hub for real-time event streaming. The server is extensible, compatible with PHP 8.2+, and designed for cloud-native deployment via Docker or Kubernetes, with graceful reloads for zero-downtime updates. It is natively supported by frameworks like Symfony and Laravel, and benchmarks show it can be up to 3.5x faster than PHP-FPM for certain applications.
